Why not reason from Adams or Early Man

source

Now it is a complex life
Tribes now considered themselves enemy
War now happened between brothers
The Cold War is a tacitly fought battle
We now intentionally suffer others
We now intentionally show power to the hapless

Why are all these issues not resolved?
Why are these issues aggravating a non-controlling atmosphere?

Why not reason from Adams or Early Man?
No more pan-Africanism
No more unity
No more love

We have more xenophobia
When don't care about unity anymore
We have more hatred

Why not reason from Adam or Early Man?
When we are all together
In one love
Blind to exposure
Full of tolerance
Where unity rules the world
